The celt codec design and implementation have been merged into the IETF Codec Working Group's "Opus" codec. As such, this repository is no longer under active development. Please see https://git.xiph.org/?p=opus.git and https://git.xiph.org/?p=users/jm/opus-tools.git for more current work. Visit http://opus-codec.org/ for more information. We apologize for any inconvenience this has caused.
